How can you ensure your presence is known when a specific directive attribute has been removed from the DOM?

I am searching for a solution to catch the attention if an element is added and then removed from the DOM. When the element is removed, I want to retrieve the ng-model value of that specific element.

For instance:

<div notify-when-removed ng-model="someTitle"></div>
<a ng-click="removeTheAboveDiv()"></a>

My goal is to access the value of "someTitle".

Answer №1

If you want to execute some code before the scope gets destroyed, you can do so using the following:

scope.$on('$destroy', function() {
  // Add your cleanup code here
});
